This is caused by legacy issue during split kolla and kolla-ansible.
this[0] line should be changed to
version_info = pbr.version.VersionInfo('kolla-ansible')
A dirty quick fix is install kolla along with kolla-ansible with the same
version.

Hey folks,
Pip install kolla-ansible is busted. I’d take ownership of this bug myself,
however, I am personally swamped. This is a DOA deliverable issue and as such
is higher priority than “critical”. Can someone in the community take a look?
